Aerospace Instrument-Making Annotation << Back METROLOGICAL ANALYSIS OF THE POWER SUPPLY CHAIN OF A TETHERED DRONE G.N. Akhobadze The issues of metrological analysis of the process of power supply of a tethered unmanned aerial vehicle, as one of the important aerial platforms for solving many vital national economic tasks, are considered. The necessity of analyzing the statistical and dynamic indicators of the blocks included in the power supply chain of a tethered drone is justified. A method for estimating errors in the transmission of electrical energy of directly interconnected blocks performing different functions of purpose is given. The results of the work can be used for metrological diagnostics of electrical signal transmission processes in measuring equipment, circuit engineering and other fields. Keywords: tethered copter, conversion, error, resistance, capacity, transfer function, engine. DOI: 10.25791/aviakosmos.8.2021.1233 Pp. 03-12.
